Radon testing
A continuous monitor on the lowest level that could be used regularly, read every hour for at least 48 hours. The written result comes the day we collect it.
4.9 rating, over 4,000 reviews NRSB-certified technicians Serving King George County
A radon test in King George is $185, or $175 when it is added to a home inspection. That is the whole price: both visits, the monitor for the full 48 hours, and the written report with every hourly reading in it. The residential rate applies to one King George dwelling. Provide directions, gate details and a reliable contact for both visits. Tell the office about base or workplace entry restrictions; residential testing cannot proceed without permission to enter the selected home.
Day 1
Drop-off
A technician places it on the lowest level that could be used regularly, following EPA placement limits and the intended use of the space, inside a two-hour arrival window. With a home inspection, placement happens during the inspection visit.
48 hours
The house stays closed
For a short-term real-estate test, EPA guidance calls for closed-building conditions for at least 12 hours before the test and throughout the measurement. Windows stay closed, exterior doors open only for normal entry and exit, and the monitor logs hourly readings that help document the test conditions during the minimum 48-hour measurement.
Day 3
Pick-up and report
A technician picks the monitor up in another two-hour window and pulls the full record on the spot. The written report reaches you the same day.

EPA testing guidance. Placement, closed-house conditions and the 48-hour minimum follow it, and your average is read against the EPA action level of 4.0 pCi/L.
Continuous monitors. Airthings Corentium Pro instruments, logging every hour for the whole test.
Appointment times are requests until our team confirms them. What the number means, how to prepare the property and the eight questions everyone asks are on the radon testing page; this page is about King George.
Virginia health officials say King George County's older low-risk map label should be moderate. That correction is a reason to test, but it cannot tell you the radon level in a King George home. A measurement in the residence is what matters to the people who live there or plan to buy it. Tell us which lower rooms are used now or could become a bedroom, office or family room so the technician can assess the right testing space.
A King George radon test needs access when the monitor is placed and again after at least 48 hours for collection. Before booking, give us the full property address, the person who can open the home on both visits, and any gate, alarm or pet instructions. Keep the test area available and avoid work that could disturb the monitor. If the property includes a separately occupied unit, mention it when requesting the test so its scope can be discussed.

Where we test in King George, and what to tell us
Courthouse and Route 3 area
For a Courthouse-area home, tell us how its lower rooms are used so the technician can assess placement.
Dahlgren-area addresses
For a Dahlgren-area appointment, share directions and any entry requirements that apply to both visits.
Fairview Beach and river-area properties
For a Fairview Beach property, test the occupied dwelling itself; waterfront location cannot predict the result.
We do not install radon systems, so we have nothing to gain from your number. If the result is at or above the EPA action level of 4.0 pCi/L, you choose who fixes it. Once the system is in, we can test again and tell you what it reads.
Virginia's residential disclosure statute directs the seller's disclosure statement to say that the owner makes no representation about whether the property is in an EPA Zone 1 or Zone 2 locality. It directs buyers to use due diligence, including reviewing EPA, Virginia Department of Health and NRSB information and ordering a radon inspection before settlement as the contract allows.
Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.

Provide exact address and entry details for both visits and keep the selected room accessible.
Yes. EPA says elevated homes can occur in every zone, which is why testing remains appropriate.
